along the spaced skids and thus -loaded on the vehicle.

1t is rthe chief object of the invention to provide .aluniversal type .skid holder-one that will hold the upper ends .of various shaped skids.

1 It is another ofbject to provide a skid holder construction which allows the upper or vehicle supported end oa skid to be quickly and easily clamped firmly in the holder socket, whether the cross sectional shape ofthe skid is rectangular, square, or round.

It isanother object to provide a -holder of this type which is capable of standing up underrough usage over a prolonged period of time without affecting its mechanical efficiency-usage in the oil eld industry, for instance.

Theinvention, together with other objects attending its production, will be more clearly understood when the `following description is read in connection with the accompanying drawings, in which:

Fig. 1 is a plan View of a holder embodying my invention, a vehicle bolster and the holder` sup-- ported end of a plank type skid being shown in broken lines;

Fig. 2 is a vertical sectional view taken along the line 2-2 of Fig. 1;

Fig. 3 is an end view of the skid receiving end of the holder, showing its socket adjusted for receiving a Wide thick lplank type skid;

Fig. 4 is a similar end View, showing the holder socket adjusted for receiving a pipe type skid; and

Fig. 5 is a schematic view illustrating the use of the holder.

Referring to Figs. 1, 2, and 3 it will be seen that the skid holder illustrated includes a variable opening skid receiving and clamping socket, designated as a whole by the numeral I0, and a heavy rigid bracket II for pivotally connecting one end of the socket to a vehicle bolster I 2.

The `bracket II is made up of a heavy angle iron strip I3, a pair of spaced bolster embracing plates, I4 and I5, each having an end welded to the inside of the angle iron I3, and three spaced pivot ears, I6-I1-I8, welded to the outside surface of one flange of the angle iron I3, in the positions shown in Figs. 1 and 2.

The plates I4 and I5 are provided with horizontally aligned apertures for receiving a bolt I9,

ture inthe bolster -I2, and serves Jtorigidly secure the bracket to vthe end of the bolster. The

ears |.6-Il-I3 are provided with horizontally aligned apertures Yfor Areceiving a pivot pin 2'I,

which serves `to pivotally support the innerend ofthe skid receiving lsocket II).

This socket lil includes a pairof elongated side plates, A2| .and 22, identical in shape, and'prefera'blyhaving a slightlyiconvex fupper edge` The lower edges of these plates include an offsetintegralfear y23, which is provided -With a plurality of vertically spaced perforations 2 4, the `perforations infea'ch plate Vbeing located identically interme- Near each of'its ends, :each plate is providedgwith any additional perforation.

The .two side plates 2i yand 22 are loosely connected `together by bars 275 and 26, which are preferably in the .form of staybolts. The boltlii passes through the perforations near the .outer endsl of the plates, while the bolt 26 passes through similarly located ones-of theperforations 2 4. A ,pivot pin in the for-m of a bar or rod 21 is ^passed through the perforations at the inner*` end of each plate 2l and 22, and through the aligned perforations in the ears IS-II-I, and thus serves to pivo-tally connect one end of the socket I0 to the bracket I I. Please note that the plates 2| and 22 are mounted inside the ears I6 and I8, and that these plates are easily slidable toward each other along the bars 25 and 26, and along the pivot ypin 21.

The socket I0 then, is so constructed that its skid receiving opening is variable in width and in height. The upper and lower surfaces of the end of a skid are embraced respectively by the bars 25 and 26. I-f the skid is thin the pin 26 is positioned in the uppermost ones of the perforations 24, as shown clearly in Figs. 2 and 3. 'I'he bar 26 may be moved to either of the lower level perforations 24 to accommodate skids of greater thickness. Similarly the plates 2I and 22 may be positioned wide apart to accommodate a wide plank type skid, and the nuts 28 and 29 tightened to clamp these plates against the side surfaces of the skid to firmly hold it in the socket. If a length of heavy pipe or a 4 X 4 is used as a skid, it is only necessary to move the side plates 2I and 22 toward each other until they contact the side surfaces of the skid, and then tighten the nuts 28 and 29 to produce the clamping action.

This invention contemplates the use of means other than the threaded staybolts 25 and 26, and Anuts 28 and 29 for urging the two plates 2| and 22 into clamping contact with the sides of a skid.

For instance, the bars 25 and 26 could have smooth instead of threaded surfaces, and a chain or cable .passed through identically located perforations 30 in the respective plates, and tightened by any suitable means, such as an 01T center lever type binder, the construction and operation of which will be well understood by those familiar with this art.

From the above description it will be seen that I have provided a skid holder which can be easily and quickly attached to the ybolster of any vehicle, and which has a variable opening socket for receiving and supporting the upper end of skids of various sizes and shapes.

Having described the invention with sufficient clarity to enable those familiar with this art to construct and use it, I make the following claims, which are considered to specically dene the ,patent protection to which I am entitled:

1. A holding device for vehicle loading skids, in combination with a bolster mounted on the vehicle, said device comprising: a bracket rigidly connected to an end of the bolster and including a pair of outwardly projecting horizontally spaced pivot ears; and a variable opening socket having one end pivotally connected between said pivot ears and its other end projecting outwardly to receive and support an end of a loading skid.

2. The invention described in claim 1 and means for varying the length and width of the opening in said socket.

3. The invention described in claim 1 in which the socket includes a pair of elongated horizontally spaced side plates, and stay bolts slidably connecting said plates and dening the upper and lower edges of the opening in the socket.

4. A holding device for a Vehicle loading skid, in combination with a bolster mounted on the vehicle, said device comprising: a pair of elongated parallel spaced side plates adapted to embrace the sides of one end of a loading skid; a pair of parallel horizontally disposed bars slidably connecting said plates at longitudinally and vertically spaced points, and adapted to receive betweenthem and embrace the upper and lower surfaces of said one end of a loading skid, the' lower level bar being located intermediate the ends of said plates, and the higher level bar being located near the outer ends thereof; and a bracket pivotally connecting the inner ends of said plates to the vehicle bolster on a horizontal pivot axis, the plates being movable along said axis.

5. The invention described in claim 4 in which the bracket includes a pair of spaced outwardly projecting ears having horizontally aligned perforations, and a pivot pin passing through said perforations and through the inner ends of said plates, the plates being slidable on the pivot pin.

6. The invention described in claim 4 and means for urging the plates toward each other along the bars.

'7. A skid holder including in combination a bolster equipped vehicle; a bracket rigidly connected to an end of the bolster and including a pair of horizontally spaced rigid pivot ears having aligned perforations therein; a pair of elongated skid supporting plates each having a perforation in one end; an elongated pivot pin passing through the perforations in said ears and in said plates, the plates being positioned inside said spaced ears, and being slidable toward and away from each other on said pivot pin; a second perforation near the opposite end of each plate; a rst stay bolt passed through the last named perforations, the plates being slidable along the stay bolt; a third perforation in each plate at aligned points lying outside and ne-- low a plane passing through the rst stay bolt and the pivot pin; and a second stay bolt pass ing through said third perforations, said stay bolts being adapted to draw the plates together to tightly embrace the end of a skid positioned between the plates and between said stay bolts.
